The new testcase FAILs on i686-linux with:
gcc/testsuite/gcc.dg/pr98807.c: In function 'foo0':
gcc/testsuite/gcc.dg/pr98807.c:20:1: warning: SSE vector return without SSE
enabled changes the ABI [-Wpsabi]
gcc/testsuite/gcc.dg/pr98807.c:19:1: note: the ABI for passing parameters with
16-byte alignment has changed in GCC 4.6
gcc/testsuite/gcc.dg/pr98807.c:19:1: warning: SSE vector argument without SSE
enabled changes the ABI [-Wpsabi]
FAIL: gcc.dg/pr98807.c (test for excess errors)
Adding usual testcase treatment for such cases.
Tested on x86_64-linux -m32,-m32/-mno-sse,-m64, committed to trunk as
obvious.
